I need solve this MCQ questions of physics

- The following equation refers to v-pendulum experiment: TA = (474 L K/ 82)-(8 n L/ 82)d, where: L: length of the string (2 meters). 7: pendulum periodic time d : distance between rods Ql k: pendulum constant g: gravitational acceleration Given that the slope of the graph (T,d ) = -14.2 s /m , and y-intercept =13.5 s4. Find the value for g: a- 10.5 m/s2 a- 9.81 m/s Can't be defined O a- 8.51 m/s2 QUESTION 2 Determine the value of the slope for the given two points QUESTION 4 ( 0.500, 7.41 ) and ( 0.800, 3.42) If T1 = 36.42 and T2 = 36.6, then the average value for T equal to: 36.5 -13.3 36.51 O -13.0 36.0 13.3 O 36 O 13.0
